The Claim

Higher adherence to the traditional Costa Rican diet is associated with significantly lower ultra-processed food intake, with adolescents in the highest adherence category consuming 29.9% of energy from ultra-processed foods compared to 43.9% in the lowest adherence category, demonstrating a clear gradient between dietary pattern adherence and ultra-processed food consumption.

In plain English

Adolescents who follow the traditional Costa Rican diet more closely consume less ultra-processed food, with those most adherent getting nearly 14 percentage points less energy from ultra-processed foods than those least adherent.

See the scientific wording

Higher adherence to the traditional Costa Rican diet is associated with significantly lower ultra-processed food intake, with adolescents in the highest adherence category consuming 29.9% of energy from UPF compared to 43.9% in the lowest adherence category, demonstrating a clear gradient between dietary pattern and UPF consumption.

Why this might work

When people eat more traditional foods like beans, rice, and fresh produce, their stomachs and brains get full with those foods, leaving less room and desire for ultra-processed snacks and drinks. Over time, the taste preferences shift to favor natural flavors, and the body stops craving the high sugar, salt, and fat in ultra-processed foods.

  1. Study: Ultra-processed food intake is associated with a displacement of the traditional diet of Costa Rican adolescents.

    Teens who eat more traditional Costa Rican foods like beans and rice eat much less junk food—those who stick closest to the traditional diet get less than one-third of their calories from ultra-processed foods, while those who eat less traditional food get almost half their calories from it.
